The most important characteristic of DNA replication is the DNA to FOLLOW THE BASE-PAIRING RULES.
Answer:
a. The operon is under positive control
a.) Loss of enzyme synthesis results from loss of regulatory R gene product which is regulated in the presence of Tis ophane for transcription. Absence of (Tis), transcription is positively controlled by regulatory Rprotein
b.) The proposed model reveals Tis / B complex prevents Tis enzymes from undergoing transcription through the RB operator by binding to the B region
the role of the R protein is
-decrease affinity of Tis / B complex to B region of RB
-bind to the R region on RB
- change the conformation of B region
- yield decreased affinity of Tis / B complex when R gene is lacking preventing transcription in the process
Effects of the RB mutations is that R protein will not bind to Tis / B complex to reduce transcription
For one thing based off of process of elimination we know that both plant and animal cells have a cell membrane, and a nucleus. Therefore we are left with cytoplasm and cell wall. According to the question we are most likely looking for something in the animal or plant cell that they don’t have in common with each other. Therefore, the answer is cell wall because an animal cell doesn’t have a cell wall, but a plant cell does. The cell wall can also make it more rigid!
